Delay Tolerant Network (DTN) is a communication
architecture enabling connectiviety in a
topology with unregular end-to-end network connection.
DTN enables communication in environments
with cross-connectivity, large delays and delivery time
variations, and a high error rate. DTN can be used
in vehicular networks where public transport get involved.

This research aims to analyze the role of public
transit as a DTN routing infrastructure. The impact
of using public transit as a relay router is investigated
by referencing the network performance, defined by its
delivery ratio, average delay and overhead. The results
show that public transit can be used as a backbone
for DTN in an urban scenario using existing protocols.
This opens insights for future researches on routing
algorithm and protocol design.
